title: The effect of EDTAC and the variation of its working time analyzed with scanning electron microscopy.
abstract: Scanning electron microscopy was used in an in vitro evaluation of EDTAC's effect on the dentinal wall of the root canal. The effects produced by varying its working time were observed. This analysis was done on twenty-four sections of roots in longitudinal and transversal cuts. After 5 minutes a certain cleansing effect on the dentinal wall as compared with the control was observed. the strongest effect was detected at 15 minutes, with no variations after 30 minutes.
